Enable DWARF accelerator tables by default when tuning for lldb (-glldb => -gpubnames)
Summary:
DWARF v5 accelerator tables provide a considerable performance
improvement for lldb and will make the default -glldb behavior same on
all targets (right now we emit apple tables on apple targets, but these
are not controlled by -gpubnames, only by -glldb).
